ROME (Reuters)- The new coronavirus was circulating in Italy since September 2019, a study by the National Cancer Institute (INT) of the Italian city of Milan shows, signaling that COVID-19 might have spread beyond China earlier than previously thought.
罗马(路透社)-意大利米兰市国家癌症研究所(INT)的一项研究显示,这种新型冠状病毒自2019年9月起就在意大利传播,这表明,COVID-19病毒可能比先前认为的更早就在中国以外的地区传播了。
The World Health Organization has said the new coronavirus and COVID-19, the respiratory disease it causes, were unknown before the outbreak was first reported in Wuhan, in central China, in December.
